In brief: Marine Corps court-martial convictions for drug possession carried the longest median confinement of any service: 9 months, across 62 convictions. A quarter of the cases received 17 months or more, and 81% of enlisted members convicted received a punitive discharge. In federal court, the median prison term for simple possession under 21 U.S.C. 844 was 6 months in fiscal years 2016 to 2025.
This post uses the U.S. Sentencing Commission's records of 6,268 people sentenced in federal court in fiscal years 2016 to 2025, compared with court-martial results from this site's Military Trial Results data (updated November 2, 2026). Acquittals and dismissals come from a second source, the Federal Judicial Center's records of 753,808 federal defendants whose cases ended in fiscal years 2016 to 2025. It is part of the Federal Prosecution Analysis series, which builds on Military Moves Toward Sentencing Guidelines to Mirror the Federal System. How the numbers were built: How the Federal Comparison Data Was Built.
Longer Confinement in the Marine Corps Records
The Marine Corps records list 62 convictions for wrongful possession under Article 112a, with trial dates from 2017 to 2025. Of those, 51 included confinement (82%). The median adjudged confinement was 9 months.
The Marine Corps median is higher than the federal median of 6 months. The longest quarter of Marine Corps sentences started at 17 months, compared with 6 months in federal court.
| Marine Corps courts-martial | Federal court, FY2016–FY2025 | |
|---|---|---|
| Convictions or people sentenced | 62 | 6,268 |
| Sentenced to confinement or prison | 82% | 70% |
| Median confinement or prison | 9 months | 6 months |
| A quarter received this or more | 17 months | 6 months |
| Pleaded guilty | 50 of 62 with a plea recorded (81%) | 98% |
| Mandatory minimum applied | See the caveats | 4% |
Punitive Discharges Were Common
Of the 58 enlisted members convicted, 47 received a punitive discharge (81%). That was 9 dishonorable discharges and 38 bad-conduct discharges. Of the 2 officers convicted, both were dismissed.
A general court-martial heard 22 of the 62 cases (35%). The federal system has no punitive discharge, so there is no federal figure to set beside these.
Pleas and Contested Cases
A plea was recorded in all 62 cases, and 50 of them (81%) were guilty pleas. After a guilty plea, the median confinement was 9 months, based on 43 cases with confinement.
In contested cases that ended in conviction, the median was 3.5 months, based on 8 cases with confinement. That is lower than the median after a guilty plea. The records do not explain the difference, and 8 cases are a small base.
Earlier and Later Trials
For trials in 2016 to 2019, the median confinement was 13.5 months, but that rests on 4 cases with confinement. For trials in 2020 to 2025 it was 6 months, based on 47 cases.
Nearly all Marine Corps convictions with confinement came from the later period, so the 6 months is the better-supported figure.
What Federal Court Reports
In federal court, 6,268 people were sentenced for simple possession in fiscal years 2016 to 2025. Of them, 4,364 (70%) received a prison term and 1,853 received probation only. Confinement was more common in the Marine Corps group than in federal court, at 82% compared with 70%.
Among federal defendants, 6,160 (98%) pleaded guilty. The median prison term was 6 months after a plea and 84 months after a trial, based on 91 people sent to prison.
The Marine Corps Among the Services
The other medians were 3 months for the Army, 3.9 months for the Air Force, and 5.5 months for the Navy. The Marine Corps also had the highest punitive discharge share among enlisted members.
The Marine Corps group is larger than the Army and Navy groups, which have 28 convictions each, and smaller than the Air Force group at 209.
| Service | Convictions, 2016–2025 | With confinement | Median confinement | Punitive discharge (enlisted) | Guilty pleas (where recorded) |
|---|---|---|---|---|---|
| Army | 28 | 86% | 3 months | 69% | 93% |
| Air Force | 209 | 93% | 3.9 months | 62% | 68% |
| Navy | 28 | 93% | 5.5 months | 62% | 74% |
| Marine Corps | 62 | 82% | 9 months | 81% | 81% |
Limits of the Comparison
Court-martial sentences are as adjudged at trial, before clemency or appeal. Federal prison terms are those imposed, not time served. Federal years are fiscal years, and court-martial figures are by trial date.
The records show nothing about the facts of any case, such as the substance or amount. The federal side counts only convicted and sentenced people, so it cannot be set beside the rate at which Marine Corps cases ended in conviction.
How We Counted
Marine Corps courts-martial with trial dates in 2016 to 2025 ending in a conviction for drug possession (Article 112a wrongful possession; federal simple possession, 21 U.S.C. 844) (62). Federal: 6,268 people sentenced under a conviction under 21 U.S.C. 844 (simple possession), any guideline, fiscal years 2016 to 2025 (U.S. Sentencing Commission).
Federal fiscal years run from October 1 to September 30. No person, judge, or lawyer is identified in any of these records.
What to Keep in Mind
Who is in each set of numbers. The federal sentencing numbers come from the U.S. Sentencing Commission. They count only people who were convicted and sentenced in federal district court. People whose cases were dismissed or who were acquitted are not in them. The military numbers come from court-martial results, which include acquittals. To compare acquittal or dismissal rates, the federal side uses a different source: the Federal Judicial Center's case data, which counts every defendant whose case ended.
Different cases reach each system. Federal prosecutors bring a narrow set of cases. In fiscal year 2024, immigration and drug trafficking cases were 59% of everyone sentenced in federal court (36,664 of 61,678). Many crimes that the military prosecutes, such as most assaults, most sexual assaults between adults, and drug use, are usually state crimes for civilians and reach federal court only in special situations, such as on federal land or in Indian Country. A federal case and a court-martial for the same crime can involve different kinds of facts.
Time periods. Federal numbers are by federal fiscal year (October 1 to September 30), based on the sentencing date. The military numbers are by trial date. Neither source has the date of the offense, so a change in law shows up in either data set gradually.
Offense categories do not line up exactly. Each comparison uses a federal offense group chosen to match the military article as closely as possible (see the crosswalk). Some matches are close; others are partial. The post says which federal guideline or statute was used and why it is not an exact match.
Drug use has no federal counterpart. Federal law does not make drug use a crime. A positive drug test is not a federal offense; a civilian can be charged only with possessing the drug. Bringing drugs onto a military installation is also a military-only offense. For these, the nearest federal charge is simple possession, and the post says that the match is not exact.
No parole in federal prison; credit for good conduct. Federal prison has no parole for crimes committed on or after November 1, 1987. A federal prisoner can earn up to 54 days of good conduct credit for each year of the sentence the judge imposed, which is about 15%. Some federal prisoners can also earn First Step Act time credits, but many offenses make a person ineligible. The numbers in this post are the sentences judges imposed, not the time people actually served.
Military confinement credit and parole. For military sentences adjudged after 2004, good conduct time is 5 days for each month of confinement, about 16%. Military prisoners can also earn up to 8 more days a month for work and programs and up to 2 days a month for special acts, with a limit of 15 days a month in total. Military prisoners can be considered for parole by their service's clemency and parole board. The military numbers in this post are the confinement adjudged at trial, not the time served.
Military sentences include punishments federal sentences do not. A court-martial sentence can include a punitive discharge (bad-conduct discharge, dishonorable discharge, or dismissal for officers), reduction in rank, and forfeiture of pay. These have no federal counterpart. A comparison of months of confinement leaves them out. A short confinement term combined with a dishonorable discharge is a heavier sentence than the months alone show.
Federal supervised release. Most federal prison sentences are followed by a term of supervised release that the judge sets as part of the sentence. A person who violates it can be sent back to prison. A court-martial cannot sentence anyone to supervision after release. Military parole and mandatory supervised release are decided later by a board, not by the judge at trial.
Who decides the sentence, and under what rules. Federal judges sentence every federal case. They must calculate the Sentencing Guidelines range, which is advisory, and must impose any mandatory minimum the statute requires unless an exception applies. In courts-martial, the accused could choose sentencing by members until the rules changed. For cases in which every guilty finding is for an offense committed after December 27, 2023, a military judge sentences alone, within sentencing parameters. Courts-martial tried in 2024 and later include both old-rule and new-rule cases, and the data cannot tell them apart.
How life sentences and "time served" are counted. In the federal numbers, a life sentence is counted as 470 months, and any other sentence longer than 470 months is counted as just under 470 months. A sentence of "time served" is counted as one day (0.03 months). Averages are affected by these rules; medians much less.
